Answer:
carbon = 7 atoms
hydrogen = 8 atoms
nitrogen = 4 atoms
oxygen = 2 atoms
Explanation:
Chemical formula = C₇H₈N₄O₂
Elements present:
carbon
hydrogen
nitrogen
oxygen
Number of atoms of each element.
carbon = 7 atoms
hydrogen = 8 atoms
nitrogen = 4 atoms
oxygen = 2 atoms
Answer:
Number of moles of Fe = 10 mol
Number of moles of CO₂ = 15 mol
Explanation:
Given data:
Number of moles of iron oxide = 5 mol
Number of moles of carbon monoxide = 25 mol
Number of moles of product = ?
Solution:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
Now we will compare the moles of reactant with product.
Fe₂O₃ : Fe
1 : 2
5 : 2×5 = 10 mol
Fe₂O₃ : CO₂
1 : 3
5 : 3×5 = 15 mol
CO : Fe
3 : 2
25 : 2/3×25 = 16.7 mol
CO : CO₂
3 : 3
25 : 25
Less number of moles of Fe and CO₂ are formed by iron oxide thus it will act as limiting reactant while CO is inn excess.
In a sample liquid water, a property that differs among the
water molecules is its own orientation and space. The explanation of the answer
to the question is because the number of the oxygen and hydrogen atoms and the
hydrogen and atoms’ arrangement will never change and will always be the same
for each of the water molecule. The strength of the bond of it also does not
change and stays the same.
